An integrated circuit test socket is adapted to use with Kelvin connectors by creating closely spaced connectors and counter-rotating links that are nested to conserve space. The connectors are shaped to make contact with a chip and communicate force and sense signals to a tester, allowing a measure of the chip's actual resistance.

A socket mount for use in connection with an integrated circuit test socket having a body with fastener holes, a plurality of electrical connector links, and a plurality of elastomer elements biasing said links, the socket mount comprising a block having a flat upper surface, a flat lower surface, and four flat edges defining a square, and respective fastener holes aligned with the fastener holes in the test socket, a first groove oriented perpendicularly with respect to a flat edge along the flat lower surface, and a second groove oriented diagonally from a first edge to a second edge along the flat lower surface, the grooves having a length equal to a length of elastomer in the test socket.

An improved test socket for testing or connecting an integrated circuit is disclosed having a platform for receiving the integrated circuit and adapted to overlay a piece of test equipment or other board, the platform formed with an array of slots each locating a portion of a two-piece connector assembly. The socket includes a conforming groove that captures an elastomer member therein while providing exposure of the elastomer member to a link assembly. The socket, with the capture groove, provides improved contact of the link assembly and reliability in locating and maintaining positioning of the elastomer member.

A thermal chamber and system for influencing the temperature of an IC chip under test including a thermal block that receives a chip socket, the thermal block adapted to be disposed between a docking interface plate and a workpress. The thermal block receives a flow of heated or cooled gas, and causes an IC chip to become heated or cooled prior to and during a test of the chip. The thermal chamber and system allows an IC chip to be testing under specific temperature conditions without using an expensive handler costing hundreds of thousands of dollars.

Integrated circuit socket connector

A socket for testing or connecting an integrated circuit is disclosed having a platform for receiving the integrated circuit and adapted to overlay a piece of test equipment or other board, the platform formed with an array of slots each locating a portion of a two-piece connector assembly. When the integrated circuit is seated on the platform, the two piece connector assemblies pivot so as to make contact between a contact pad on the IC and the board for establishing or evaluating signal transmission by the IC. The platform houses a resilient tubular member that biases the connector assembly in a disengaged position out of contact with the board or test equipment. When the IC is placed on the platform, the bias of the resilient tubular member is overcome and an electrical connection is established across the connector assembly.
